A case study focuses on a single individual, a small group of people, or occasionally a single event. You'll be conducting qualitative research to find specific details and descriptions of how your subject is affected. 1  For example, a medical case study might study how a single patient is affected by an injury.ou may be asked to prove that the case study does no harm to its participants. 1  Follow this step even if you are conducting a retrospective case study. 2  In some cases, publishing a new interpretation can cause harm to the participants in the original study.
Formula or Equation Note. The incremental capital output ratio (ICOR) is defined as the ratio between investment in some previous period(s) and the growth in output in the subsequent period.Needless to say, ICOR calculation is based on constant price data.ormula or Equation Note.

A marginal variable which is greater than the average variable will increase the average variable, a smaller than average marginal variable will lower the average variable. Short Run Costs Total Cost (TC) is the cost of all the productive resources used by the firm.hort Run Production Process To increase output in the short run, a firm must increase the amount used of a variable input. Three relationships are crucial in this period. (Assuming labor is the only variable input in the following discussion.) Total Product (TP or Q) is the total amount of output produced.
